Shared Commander Delete... why?!

In a shared PvP battle, I have had people rage-quit on me, deleting all commanders just because they lost their commander and foothold on a planet they started on. Why is this even a thing?!? Personally I believe only I should have the right to commit suicide... not my team mate who decided if he's going down everyone is.

This ruins a great deal of shared multiplayer for me and is a non-mechanic in the game. (At what point is deleting someone else commander going to help... they little damage when they blow up anyway).

Worse, I can see this as a reason people stop playing any team multiplayer and PA has enough trouble with getting new players as it is.
